What changed at the same time
The fastest decline of "Fertility (TFR)" was in 1967–1977: 4.69 → 3.17. Over the same years: births 5.66k → 5.32k; population 162k → 219k; urban share 61.9% → 70.6%; no data for the others in those years.
Over the last 10 years (2013–2023): fertility (TFR) 1.74 → 1.37; births 5.27k → 4.34k; population 379k → 399k; internet 72% → 92.4%; urban share 82.4% → 81.3%; GDP per person (PPP) 32,403 PPP dollars → 35,221 PPP dollars; GDP growth −2.9% → 3%; inflation 0.4% → 3.1%.
How the indicators relate
Fertility (TFR) and internet (1990–2023, 30 years): levels are strongly related, in opposite directions (r = −0.96); year-to-year changes show no reliable link (r = −0.19). This looks like a shared trend: both change over time, but not in step from year to year.
Fertility (TFR) and urban share (1960–2023, 64 years): levels are strongly related, in opposite directions (r = −0.97); year-to-year changes show no reliable link (r = −0.26). This looks like a shared trend: both change over time, but not in step from year to year.
Fertility (TFR) and GDP per person (PPP) (1990–2023, 34 years): levels are barely related (r = −0.26); year-to-year changes show no reliable link (r = −0.18).
Forecasts vs actual
Fertility (TFR): past UN projections. The outcome was below the projection in 11 of 11 revisions (1998–2022) and above in none; median gap −24%.
Fertility (TFR): UN 2024 projection (medium): 2050 — 1.41 (+3% vs 2023), 2100 — 1.51 (+10% vs 2023); low variant for 2100: 1.01.
Births: past UN projections. The outcome was below the projection in 11 of 11 revisions (1998–2022) and above in none; median gap −20%.
The UN 2002 projection did not expect today's level (4.34k, 2023) before its horizon ended (2047).
The UN 2017 projection did not expect today's level (4.34k, 2023) before its horizon ended (2097).
Births: UN 2024 projection (medium): 2050 — 3.77k (−13% vs 2023), 2100 — 3.36k (−22% vs 2023); low variant for 2100: 1.34k.
Population: past UN projections. The outcome was below the projection in 6 of 12 revisions (1998–2022) and above in 6; median gap −0.2%.
The UN 1998 projection expected this level (399k) already around 2021: reality is 2 years behind it.
The UN 2019 projection expected this level (399k) already around 2021: reality is 2 years behind it.
Population: UN 2024 projection (medium): 2050 — 424k (+6% vs 2023), 2100 — 385k (−4% vs 2023); low variant for 2100: 263k.
GDP growth: IMF next-year forecasts (34 editions, 2007–2023). On average the outcome was 1.6 pp below the forecast; below it in 62% of cases; typical error ±4.3 pp. The biggest miss was for 2020: IMF, April 2019 expected 1.6%, the outcome was −20.1%.
GDP growth: latest IMF forecast (IMF, April 2026): 2025 — 2.8%, 2027 — 1.9%, 2031 — 1.5%.
Inflation: IMF next-year forecasts (34 editions, 2007–2023). On average the outcome was 0.3 pp below the forecast; below it in 56% of cases; typical error ±1.3 pp. The biggest miss was for 2024: IMF, April 2023 expected 3.4%, the outcome was 0.4%.
Inflation: latest IMF forecast (IMF, April 2026): 2025 — 0.6%, 2027 — 1.9%, 2031 — 2%.
UN projections vs actual
Solid line: actual data, UN WPP 2024 estimates to 2023, then national statistics where comparable with the UN. Dashed: medium variants of past UN revisions. The table shows what each revision expected for the latest year (or five-year period) with actual data.
